CORRECTIVE ACTION
WARNING
Dry cleaning solvent P-D-680, used to clean parts, is potentially dangerous to personnel and
property. Use in a well ventilated area as the fumes are dangerous if inhaled. Do not use near
open flame or excessive heat. Flash point of solvent is 100 . -1380F. (38 . -59 . ).

compressed air.
(3) Inspect element for excessive wear or loss of capacity to retain dust and dirt.
Replace a defective element.
(1) Install the T-stud (21), ferrule (20), upper cover (19), plate (18), separator (17),
element (16), screen (15), lower cover (14), and wing nut (13).
(2) Tighten wing nut finger tight.
Step 2.
Check V-belts for proper adjustment. Also make a visual inspection of belts and condition to
determine if the belts require removal for cleaning and deglazing. If deglazing appears necessary,
remove the lock belt guard.

b. Use a cloth dampened in dry cleaning solvent P-D-680 to remove oil and dust film. If
the belts appear to have been saturated, and the heat has glazed the surfaces of the Vee's,
proceed as follows:
c. Use a medium grade of grit sand paper (not emery cloth) and rough up the surface
with strokes of uneven direction.
d. Wipe off all grit particles. When surfaces have been d eglazed, install the belts on

When installing new belts, never pry the belts over the pulley grooves.
on the V-belts. Depress one of the V-belts midway between the pulley and flywheel; when the
top lines up with the bottom of the belts next to it under normal thumb pressure the tension
is correct.
CAUTION
Do not adjust the V-belts too tightly as this will overload motor and compressor bearings.
Also check and be sure pulley alinement is maintained.
f. Tighten motor mounting bolts securely.
Step 2.
Check oil level in crankcase for low oil.
Remove fill plug in crankcase and fill to level in accordance with LO 54310-356-12.
